Strategic Double Clicking

Here's another list of factors that need a triple-check but could use some extra trial factoring love first:

I'll do them all.

If anyone is interested in doing a quint check, I just checked in my result for this one which didn't match any of the previous 3.

It should be able to be manually assigned from the website.

Mine.

You should try it with a bit higher FFT, just to make sure! (it is at the very limit/border of its FFT range, I assume that is why the multiple checks)

Not a factor to be found!

How? The line in my worktodo.txt looks like this currently:

DoubleCheck=<aid>,39138553,71,1

and I'm using mprime.

I swear sometimes the assignment ids almost look like English. Is PrimeNet sentient?

Connect once to the server to make sure you got the assignment for your name (if not already).
Stop mprime, delete the checpoint files (otherwise it will resume from there)
edit your worktodo to add the red text
DoubleCheck=your_key_or_use_N/A,FFT2=2304K,39138553,71,1
(it works with P95, don't know if it works with mprime).
It will take a bit longer (plus the time you already lost for this assignement, which is... lost, if you delete the checkpoint file) i.e. your ETA will extend with few hours.

Done.

If it was on the edge of some FFT boundary, wouldn't mprime or prime95 do it's thing where it tests a few iterations to see if the roundoff error is > than whatever 0.24'ish value?

Even then, let's say there was a roundoff > 0.4 somewhere during those runs, the error code would have reflected that, even if it was repeatable and it used the slower method or whatever.

In this case, all 4 runs (including mine) have an error code of zero. That's not to say the FFT size it used wasn't a factor, but hopefully both Prime95 and mprime are doing that basic little test if it's close enough to matter.

I do sometimes get roundoff > 0.4 for work where it didn't do the FFT test initially, and sometimes I've had the roundoff error when it did do that test, but I don't recall if it ever mattered whether it chose the lower or higher FFT size. I can't really say.

Probably doesn't matter, but just FYI, I hid the assignment ID in the posts above. Worst thing that could happen is someone submits a call to unassign the work and then they check in their own result first... silly hijinks aside, I don't think the AID is all that critical, but just in case. LOL
